PyAlsaAudio refuses to compile with errors

[DanRPI]

i tried to install pyalsaaudio with pip3 (to get another script running) (as root on a RPI1, Raspbian GNU/Linux 8 (jessie) 4.19.118+ #1311 Mon Apr 27 14:16:15 BST 2020 armv6l GNU/Linux)

pip3 install pyalsaaudio

i did the same for pyaudio which worked after i installed libportaudio2 and portaudio19-dev so it doesn't seem to be due to pip3 or phyton itself (which i both installed to get...........) i really don't like this system bloating loops one has to make to get things working... in 2k one could start a desktop computer with a 350MB Linux, now one needs 2gig for a stripped version minibian for a single platine rsc computer...

got it working a "md m4" is missing in the autoconfig

[DanRPI]

a little more detail as requested, from memory, it was some weeks ago, and in plain speak, i'm not that expert...

• during the depacking script of the modules i noticed an error reading the like "folder m4 is missing ... extracting to" and a while after these files were missing in the compile run.
• so i simply made this folder at the expected location,
• and in the next run the files went there while extraction and were finally found in the compile run...

As a work around it may help to specify c99 as the C++ specification. So, in the file setup.py:

ext_modules=[Extension('alsaaudio',['alsaaudio.c'],
                               libraries=['asound'],
                               extra_compile_args=["-std=c99",]
        )]
